Steve, The 40 meter thing sounds a bit like you are tuning up on a spur combination. Had a very similar thing on a T4XB. Seems to me that I found the xtal osc was not working correctly. But I will stress to look for the most simple things first. Your 100 watts out, use a receiver to make sure what you are a clean note and on the freq you think it is, then reevaluate.

Actually, I did re-do the caps that would have caused the most damage (the bias caps). I've also found that I can get 100W out easily on 40m but zero on 20. This is starting to look like I've got to take the covers off again and clean the switch wafers again. I don't think I cleaned the one in the final cage. Hmmmm.

Bad power supply caps can be a nightmare in these situations and rear their ugly heads just like this. If not, might be time for an AC-4R order from the Heathkit Shop, hi. 73, Don, WB5HAK No virus found in this incoming message.
